I make and sell small cedar boxes. About 300 a year now for over five years. I inlay images into the hinged lids.
The item that I make the most money on is rubber band shooters. I sold seventy two of them at a pumpkin festival in a very small west Texas town this past Saturday. I use free materials I get from builders scraps and make four per hour and sell them for $5 each.!https://s3.amazonaws.com/vs-lumberjocks.com/nw6wkkh.jpg!

Trivets, Christmas ornaments, picture frames, what’s your fascination? Go to a craft show & see what folks are buying. If you’re scroll saw inclined, put your mind to work. What does the Mrs. Need in her kitchen? Bathroom? Etc.?

Getting the wife’s opinion is a good idea. Take wife to craft show to get ideas. Realistically, you are trying to sell mostly to women. Do not just make things that you like. Too often you will just take them home. As much as possible, try to be unique. You want it to appeal to customers, but you don’t want it to be just like everyone else’s. Customers like something special.
